predict the solubility of 2-propanol in dichloromethane and in water.

Can someone explain how they came to their conclusion because I just don't understand how to determine solubility.

You didn't say what conclusions THEY came to.
Like dissolves like. Water is a polar solvent and contains OH group. 2-propanol contains OH group and the organic part is not overwhelming so it should be soluble in water. I would not expect much solubility in dichloromethane since it contains no OH groups and is not highly polar.
